all whom it may concern:

Be it known that l, l'lAitllY lhcx'rtnr, a subject of the Kingot the linited Kingdom o1 Great- Britain and Ireland, and residing at Whitehaven, Cumberland. England, ha Ye invented a 'lWW and useful Improvement in lloller-Bearings for llrongh-Conveyors, &c., of which the following is a specil'ication.

This invention relates to reciprm-atingr.

trough conveyor combined screens and coin yeyers. jigging screens, picking belts, and the liktu and has for its object to provide suitable selt adjusting anti-friction bearings for devices of the kind retort-ed to, the reciprocating troughs or the like being moved up and down as tl are reciprocated back and. forth by virtue of stationary bearings between which and scl'fadjusting bearing" movable with the trough or the likc antiion balls or rollers are interposed.

in the accompanying drawing l l tillt'es l and '2 are vertical sectional views, at right angles to each other, illustrating one of the improved bearings and showing a portion oi a reei 'n'ocating trough and l ig'. E3 is a cross section of the trough showing the bearings in i eign matter from entering the ball races and oil-containing receptacles between the said parts A and B. The stationary brackets or supports B are provided with inclined bearings or ball races, and oil containing receptacles K, and the movable brackets A are provided with self-adjusting, semi-circular fittings or hearings A the rounded portions of which fit in correspont'ling sockets in the brackets A. Between the fittings or bearings A. and the inclined portions or raceways on the supports B are interposed antitriction balls or rollers contained in the reeept'acles K, which latter are preferably partly filled with oil for lubricating the Aside from the protection affordgrooved flanges a which receive l'langes on the brackets or supports P), to 'lorin loose dust-locks, the bearings are preferably further protected by flexible covers ill of leather or other suitable material alatached to or connected with the parts A and i3.

'lhe troughs or other reciprocating parts ll may be operated, so as to be moved back and forth, in any suitable manner, and as they are rcciprocattal' back and forth they will be moved up and down by virtue of the int-lined race ays hereinbefore describcth and in such movements the scnii-circnlar bearings.

ed by the bearings or fittings A will be self-adjusting to acconnnmlate the dilt'erent positions of the parts. as will be understood.

llaring thus described my invention 1 claim and desire to secure by Letters Patent oi the United States:

in a machine of the character referred to, the combination with a, reciprocating part provided with inclined bearings movable with said part, of a support provided with inclined raceways, anti-friction rolling devices interposed between said inclined bearings and raceways, the bearing members on said reciprocating part; having semi-circular self-adjusting fittings socketed in said reciprocating part: and engaging said rolling de vices.

In testin'iony whereof I have signed my name to this specification in the presence ol two subscribing witnesses.
